Feb 13, 2004 · We show that light stabilizes nuclear CO protein in the evening, whereas in the morning or in darkness the protein is degraded by the proteasome. Photoreceptors regulate CO stability and act antagonistically to generate daily rhythms in CO abundance.

CONSTANS is an evolutionarily-conserved central component of the genetic pathway that controls the onset of flowering in response to daylength. However, the specific biochemical mechanism by which the CONSTANS protein regulates the expression of its target genes remains largely unknown.

Jan 14, 2011 · An interesting link between flowering and DELLA proteins, connected to both ethylene and GA signalling, has recently been proposed ( Achard et al., 2007 ), but these proteins appear in vascular plants and are absent in algae, so this mechanism is not as evolutionarily conserved as photoperiodic signalling.
